Light extraction elements
First Claim
1. A light guide comprising:
- a first major surface;
a second major surface opposite the first major surface;
an array of extraction elements, each extraction element disposed between a corresponding upper flat surface of the first major surface comprising an upper edge and lower flat surface of the first major surface comprising a lower edge, each corresponding upper edge and lower edge defining a plane therebetween, each extraction element comprising;
a first face adjoining the upper edge, the first face projecting inwardly relative to the plane at a first angle;
a second face adjoining the first face, the second face projecting inwardly at a second angle relative to the plane, the second angle greater than the first angle;
a third face adjoining the lower edge and the second face, the third face projecting inwardly relative to the plane at a third angle, the third angle greater than the first angle;
wherein the first face, second face and third face define an indentation projecting inwardly from the plane defined by the first major surface.
